Best out here is a Smokin Joe's. Not sure why but they don't do brisket, and instead offer tri-tip.
Asked why once and the guy couldn't or wouldn't tell me.
Good friend did the Salt Lick pilgrimage a while back and her pictures of the food and place were ridiculous.
Them and Franklin are on the bucket list.
The Salt Lick BBQ in Driftwood - about 1/2 hr SW of Austin. I've been to Franklins and Snows. Salt Lick in Driftwood TX is better. Best get their early though.
